Bring a large saucepan of water to a boil. Salt the water. Prepare a large bowl of ice water.
Add the green beans to the boiling water. Cook until the beans are tender-crisp, 1 to 2 minutes. Drain and immediately transfer the green beans to the ice water to stop them from cooking further. Drain and transfer the beans to a serving bowl.
Add the kidney beans, chickpeas and parsley to the bowl. Stir to combine.
Add the dressing to the beans. Toss to combine. Serve.
The dressing:
In a small bowl, whisk together the lemon juice, agave nectar, thyme, salt and pepper. Slowly whisk in the olive oil.
